SOLVED - Used a backup to refresh deleted files.

Long story short:


1. I ran out of disk space, so I got by using putty (using root), and deleted some files.

2. Logged in to the machine using my non-root user (rakesh) login credentials.

3. Ran Bleach-pit as root and deleted files, logs, etc.

4. Reduced size of my swap file from 2G to 1G.

5. Rebooted, unable to login to GUI by username rakesh. But, able to login through putty by using username Root and rakesh

Here is authication log file:

Thank you for your assistance.

Edit:

Able to login with using webmin using username root, but not rakesh.
Can login using putty using both usernames root & rakesh


Edit#2
I created another account by using webmin. I was unable to login to the new account also.

If you know which files you removed that broke things, it might be helpful to others if you share that.
